Valid for Submission
N60.49 is a billable diagnosis code used to specify a medical diagnosis of mammary duct ectasia of unspecified breast. The code N60.49 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code N60.49 might also be used to specify conditions or terms like galactophoritis, mammary duct ectasia, periductal mastitis or plasma cell mastitis.
Unspecified diagnosis codes like N60.49 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Mammary duct ectasia
- Periductal mastitis
- Plasma cell mastitis

|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|600||NON-MALIGNANT BREAST DISORDERS WITH CC/MCC||09||0.9957|
|601||NON-MALIGNANT BREAST DISORDERS WITHOUT CC/MCC||09||0.6876|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert N60.49 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code N60.49 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Most women experience breast changes at some time. Your age, hormone levels, and medicines you take may cause lumps, bumps, and discharges (fluids that are not breast milk).
If you have a breast lump, pain, discharge or skin irritation, see your health care provider. Minor and serious breast problems have similar symptoms. Although many women fear cancer, most breast problems are not cancer.
Some common breast changes are
- Fibrocystic breast changes - lumpiness, thickening and swelling, often just before a woman's period
- Cysts - fluid-filled lumps
- Fibroadenomas - solid, round, rubbery lumps that move easily when pushed, occurring most in younger women
- Intraductal papillomas - growths similar to warts near the nipple
- Blocked milk ducts
- Milk production when a woman is not breastfeeding
